Limestone is typically old ocean bivalves and early plant like animals. I can't tell what specifically you have found from the pics sorry. But I bet some other people here can help. Some of the tube like bits look a lot like crianoids. Nice find!
Thank you! I appreciate every bit of information I can get. I honestly don't expect anyone to tell me exactly what it is, but opinions are greatly appreciated.
Lols! I'm here because in my normal limestone fossil finds of crianoids braciodods and sea urchin spines I've been finding human artifacts that I know nothing about!
